IMPROVEMENT IN DRIVING P'ADDLE-WHEELS.

Specification forming part of Letters Patent No. 115,380, dated May 30, 1871.

I, JOSEPH M. STORY, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain Improved Mode of Driving My invention relates to'the manner of applymay be drawn together by a series of levers or screws with a large friction-wheel on the shaft of the paddle-wheel and a smaller frictionwheel on the driving-shaft of the engine.

Figure 1 is an elevation of a steamboatwheel, showing the application of myinvention thereto. Fig. 2 is a plan of the same. Fig. 3 is a modification of the device for drawing to- A is thepaddle-wheel, secured to the shaft B. -A friction-wheel, C, having as large a diend of the paddle-wheeL; Two small frictionframes all), respectively. They are in contact posite side with the smaller friction-wheel F boat. A shaft, H, journaled in each upright doublecranks d d turned in opposite directions. .Theyareconnected, by means of pitmen 6 c, with the inner ends of the sliding frames. f is a lever attached to the end of the shaft H outside of the frame 0. In place of the above=described device for drawing together the moving frames, in which are located the small friction-wheels, aratchet bar, g, engaging the pinion h secured to the nut i, which has a right-and-left-hand thread within it to receive the screw-rods k l, imparts motion to the two frames.

Motion is imparted to the large friction wheel 0 attached to paddle-wheel of the steamboat, or to the shaft thereof, by the twosmall friction-wheels D and E, which are rotated in the same direction by the friction-wheel F on the driving-shaft of the engine. The faces of these four wheels are kept in such close con tact as to prevent slipping by means of a a weighted lever, f, acting through eccentrics or cranks on the shaft H, and pitmen connected therewith on the sliding frames at and b, in which are journ aled the two intermediate fric tion-wheels D and E, drawing them in between the driving and large friction wheels.

I claim-as my invention The two intermediate friction-wheels E and D and the sliding frames at and b, when combined to operate substantially in they manner and for the purpose specified.
